The internet is a conundrum, it is a vast resource and wasteland of good information. I've been surfing and searching all over about info on fuel injectors on 22res and I probably should have just come here first
On my '93 4Runner I have one really loud injector (#4) and I can't stand it. The truck has 113k on it so I expected to have to do some work on it when I bought it recently. I felt pretty sure when I drove it that it was a very familiar Toyota sound and went ahead and bought it. I finally had time this week to really check and do the "mechanic's stethoscope" gag on the motor. The top end and bottom end of the motor sound great all around. Just a bunch of whirring. I then checked the injectors and although they are all somewhat noisy, #4 is a real clanker. I stuffed my hands in and finally got it unplugged and ran the engine with #4 disconnected. Other than a rougher idle, it ran fine and no clatter. Although that would change stresses on the piston, I really don't think the problem is a rod bearing or anything else as the sound stays consistent no matter the engine temp.
So, anybody know a good place to buy good injectors? This truck isn't going to be fancy so even good rebuilds would be fine with me as long as they are OEM. Also, what sort of price is reasonable? I've found everything from this place:
http://store.yahoo.com/dpstore/fuel-injectors-toyota--4-runner.html (if anybody knows what w/jecs-- stands for I would appreciate it too, I haven't had time to check)
to other sites with single injectors costing upwards of $130.
Any info would be appreciated 'cause I can't stand the sound of it!
